I am working on a system whose state sapce model is defined as follows:

x = A*x + B*u;

y = C*x;

where, x is state variable with dimension (15*1), y is the output variable with dimension (6*1) and u is the input variable with dimension (3*1). The dimensions of matrices A, B and C are (15*15), (15*3) and (6*15), respectively. I want to implement the Particle Filter block of MATLAB simulink for state estimation of this system. The simulink model of the Particle Filter is given below:

Fig 1

The Particle Filter configuration parameters are given below in Fig 2.

Fig 2.

When I run the simulation, it shows the following error:

Please help me debug the above problem.

Hello @UPASANA SARMA

The error message suggests an issue with the input size in a Simulink model. To fix this, please change the “Number of particles” parameter from 1000 to 1000000. The property that needs updating is highlighted in the image below.
